Helium reminds this reviewer of Rohinton Mistry’s Such a Long Journey. Both books are essentially fiction but based on contemporary events in India. The background of Mistry’s novel is the period when Indira Gandhi was the country’s prime minister (the writer had some unflattering things to say about her and, as a result, the film based on the book was banned in India). Jaspreet Singh’s theme is narrower—the November 1984 anti-Sikh riots that followed Indira Gandhi’s assassination. The riots thread their way all through the book, linking the main characters together. Curiously enough, both Jaspreet Singh and Rohinton Mistry are ethnic Indians based in Toronto, Canada.
